Gadila is a genus of small tusk shells, which are marine scaphopod molluscs in the family Gadilidae.
Shell decidedly curved; more or less swollen near the middle or toward the aperture; more tapering toward the apex; apical orifice not contracted by a callous ring; or with such callous ring, weak and far within. Edges not slit.
— Pilsbry and Sharp, original genus description
Species within the genus Gadila include: [2]
Chitons are marine molluscs of varying size in the class Polyplacophora, formerly known as Amphineura. About 940 extant and 430 fossil species are recognized.
The tusk shells or tooth shells, technically the Scaphopoda, are members of a class of shelled marine mollusc with worldwide distribution, and are the only class of exclusively infaunal marine molluscs. Shells of species within this class range in length 0.5–18 cm (0.20–7.09 in). Members of the order Dentaliida tend to be larger than those of the order Gadilida.
Dentaliida is one of the two orders of scaphopod mollusks, commonly known as elephant's tusk shells. The order Dentaliida contains most of the larger scaphopods, and is distinguished from the other order by the shape of its shell, the shape of the foot, and the arrangement of some of their internal organs.
Achatinella is a tropical genus of colorful land snails in the monotypic Achatinellidae subfamily Achatinellinae.
Bulimulidae is a taxonomic family of medium-sized to large, air-breathing, tropical and sub-tropical land snails, terrestrial pulmonate gastropod molluscs in the superfamily Orthalicoidea.
Planorbidae, common name the ramshorn snails or ram's horn snails, is a family of air-breathing freshwater snails, aquatic pulmonate gastropod molluscs. Unlike most molluscs, the blood of ram's horn snails contains iron-based hemoglobin instead of copper-based hemocyanin. As a result, planorbids are able to breathe oxygen more efficiently than other molluscs. The presence of hemoglobin gives the body a reddish colour. This is especially apparent in albino animals.
Gadilida is an order of very small tusk shells, marine scaphopod molluscs.
Cadulus is a large genus of small tusk shells in the family Gadilidae. It contains over fifty-one described species.
Clausiliidae, also known by the common name door snails, is a taxonomic family of small, very elongate, mostly left-handed, air-breathing land snails, sinistral terrestrial pulmonate gastropod mollusks.
Streptaxidae is a family of carnivorous air-breathing land snails, terrestrial pulmonate gastropod mollusks in the clade Stylommatophora. Six Streptaxidae subfamilies are accepted in the 2005 taxonomy of the Gastropoda by Bouchet & Rocroi.
Dentalium is a large genus of tooth shells or tusk shells, marine scaphopod molluscs in the family Dentaliidae. The genus contains 50 described species and about 50 extinct species.
Chilina is a genus of air-breathing freshwater snails, aquatic pulmonate gastropod mollusks in the superfamily Chilinoidea.
Hyperaulax ridleyi is a species of tropical air-breathing land snail, a terrestrial pulmonate gastropod mollusk in the family Odontostomidae.
Pyrgospira aenone is a species of sea snail, a marine gastropod mollusk in the family Pseudomelatomidae.
Monilea is a genus of sea snails in the family Trochidae, the top snails.
Polyschides is a genus of gadilid tusk shell (scaphopod).
Fustiaria is a genus of scaphopods in the order Dentaliida and is the only genus comprising the family Fustiariidae, with 24 species.
Siphonodentalium is a genus of small tusk shells in the family Gadilidae.
Compressidentalium is a genus of tusk shells, marine scaphopod mollusks.
Dischides is a genus of molluscs belonging to the family Gadilidae.
